WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent N 0. 415,989, dated November 26, 1889. Application filed November 10, 1888. Serial No. 290,469. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH VVOODHAMS, a citizen of the United States,'residing at Detroit, in the county of IVayne and State of Michigan, have invented certain new and useful Improvements in WVindow-Screens, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to new and useful improvements in window-screens; and the in vention consists in the peculiar construction of the adjustable wings or extensions of the screen, all as more fully hereinafter described, aud shown in the drawings, in which Figure 1 is an elevation of my improved screen with the front portion of the lower rail broken away to show the construction thereof. Fig. 2 is a horizontal section on line a: 00 in Fig. 1. Fig. 3 is a crosssection on line y y in Fig. 1. Fig. at is an enlarged perspective of a portion of the screen; and Fig. 5 is a perspective view of the screen as in its first stage of manufacture, as hereinafter specially referred to.

The peculiar construction and operation of my improved screen will be best understood by describing the Various steps in its manufacture, which are as follows:

First, I construct the screen shown in Fig. 5, which consists of the side rails A and top and bottom rails 13, to which the wire fabric 0 is secured in any suitable manner, preferably by securing the edges of the fabric by means of little strips D, secured in corresponding grooves formed in the frame of the screen, as in the ordinary manner of c011- structing screens. Upon the top and bottom rail of the screen I then secure the strips E (in such manner as to form between them the longitudinal grooves or recess F, open at both ends) to suitable wings G, adapted to form the lateral extensions of the screen. I then secure near the upper and lower corners the wires H, the inner ends of which are doubled up to form loops I. These wires are secured to the wings in such relative position to the frame as to coincide with and engage into the grooves F, as shown. Between the inner ends of each pair of wires I loosely place a coil-spring J, and transversely through the frame I drive a tack or nail K, which engages into the loop of the wire to prevent the outward withdrawal of the wings farther than their width will permit. I finally finish the screen by covering over the groove in the top and bottom rail by a suitable strip L, which gives a finished appearance to the face of the rail.

It will be'readily understood that by the simple means of constructing the wings they are-made to extend automatically through the action of the springs J, which press against the inner ends of the loops on the wires II. It is obvious that the loops have to be spread out enough at their inner ends to prevent the'springs from slipping over them. The outward extension of the wings beyond the desired limit is prevented by the nails or stops K, and the inward compression is limited by the impingement of the wings against the ends of the strips E.

The advantage of my construction is that it is very economical in the use of lumber and requires but little labor, as all the parts may be manufactured without the use of any special machinery.

I am aware that spring-actuated extension-wings to window-screens are not new, and do notseek to cover such, broadly. My construction is cheaper and simpler, more durable, and easy to repair in case of breakage or disorder of the parts.

hat I claim as my invention is 1. In a window-screen, the combination, with the frame of the screen having the longitudinal grooves F formed in the top and bottom rails thereof, of the extension-wings G, the two independent wires H, engaging into these grooves and having the loops I formed thereon, the stops K, engaging into these loops, and the springs J placed into the grooves between the ends of the loops and connected at their ends to said loops, all arranged to operate substantially as and for the purpose described.

2. In a window-screen, the combination, with the frame composed of the top and bottom and side rails, of the strips E, secured to the top and bottom rails with a recess F between them open at the ends, the wings G, In testimony WhereOfI affix my signature, in thefabri'cO, the Wires secured to the wings presence of two Witnesses, this 20th day of [o and located in said recesses, coil-springs in October 1888.
